Flavonoids and other compounds from Vitex limonifolia

Abstract

Using combined chromatographic methods, three flavonoids, 5,4'-dihydroxy-3,7-dimethoxyflavone (1), vitecetin (2), 5,4'-dihydroxy-7,3'-dimethoxyflavone (3), a lignan, verrucosin (4), and a ᵧ-pyrone glycoside, maltol O-β-V)-glucopyranoside (5) were isolated from the methanol extract of the leaves of Vitex limonifolia. Their structures were identified on the basis of spectroscopic evidence and comparison with those reported in the literature. Compounds 1 and 3-5 were reported from Vitex genus for the tirst time.
